2. Introduction

Completing the challenge with a minimum score of 100 points allows the candidate to participate in the selection of the online course "Acelera Dev - Python", sponsored by Stone. The course covers Python topics, from beginner to advanced, going from basic language to deploying a complete web application project. Students are evaluated by criteria such as: proficiency in the code, contribution to the course community, commitment to classes, concern with the state and organization of the written code and cooperation with other students.

3. The challenge

Write a program, in any programming languagem, that makes a HTTP GET request to the url below:

https://api.codenation.dev/v1/challenge/dev-ps/generate-data?token=YOUR_TOKEN

The result of request will be a JSON like this:

{
	"numero_casas": 10,
	"token":"user_token",
	"cifrado": "encrypted text",
	"decifrado": "decrypted text",
	"resumo_criptografico": "hash code"
}

3.1. Steps

---

3.1.1. Step One: Save the JSON in a file

---

The first step is to save the content of the previous request inside an JSON file named answer.json.

3.1.2. Step Two: Decrypt the text

---

You might use the number of places (numero_casas in JSON) to decrypt the text and update the JSON file in the decifrado field.

3.1.3. Make a hash code from the decrypted text

---

Use the decrypted text to make a hash code with the SHA1 algorithm (with any programming language) and update the JSON file again.

3.1.4. Send via POST to Codenation API

---

Your program should submit via POST the updated JSON file to this url:

https://api.codenation.dev/v1/challenge/dev-ps/submit-solution?token=YOUR_TOKEN

OBS: The API expects a file to be sent as multipart/form-data, as if it were sent by an HTML form, with a field of type file with the name answer. Consider this when uploading the file.

4. Result

This challenge allowed me to enter the "Acelera Dev - Python" classroom as a "spectator" with the same responsibilities as a regular student (including the same tasks and scores being evaluated), but monitored by other companies that have a partnership with Codenation.
